I don't know, but when you figure it out let me know!
I have over 12,000 hours with close to 5000 widebody command, and all I have learned is nobody is immune to a bad landing now and then. In big jets being smooth is really not the goal or most important thing, ( but I know having a bad landing seems to haunt you for days).
Your experience level is still low and it will get better......try and be a sponge and absorb as much good knowledge as you can from those you fly with and you will be fine.
